4 small things the upcoming Galaxy S4 should have

An 1080p display and zippy A15 CPU's are no-brainer's, but here are some less obvious but still importantthings.1. No front hardware buttons, there's no need for them and they hinder innovation.2. A nice design that matches its high-end statues.3. Revised designs for touchwiz icons.4. A dark black front design, to fit in with the Amoled display (as in the Galaxy S2).
